Connection chi, the rotation connection chi are provided with four and rotate per root and be provided with chi groove and junction button on connection chi, described turn
The next junction button of dynamic connection chi is buckled in a chi groove for rotating connection chi and is mutually fastened and connected.
Further, the Main shoe plate side is further fixed on handle button, and the Main shoe plate opposite side is also connected with
There is handle, the handle button is mutually snapped connection with handle end, for portable, take conveniently.
Further, the intermediate ends of the ruler are further fixed on ruler rotary shaft, the doubling of ruler can be deposited.
Further, the left and right two ends of the ruler are embedded on the inside of drawing board groove, can move up and down convenient picture.
The beneficial effects of the utility model are：A kind of this practical Multifunction middle-school mathematics teaching teaching aid is provided with left and right
Two pieces of main supporting plates, the handle that can clasp opposite side by handle when early not using are fastened, and are conveniently taken, and main supporting plate is carried on the back
Portion is further fixed on magnetic piece, can directly adsorb on blackboard, while being also associated with rotary moveable plate, can stand upright on desk or say
Explained on platform, and on the inside of main supporting plate, be provided with ruler and four rotation connection chis, ruler can be turned down and be stored in ruler
In fixture block, and rotate connection chi and can arbitrarily rotate and stretch to be drawn, facilitate teacher's explanation trigonometric function related content.
Description of the drawings
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or accompanying drawing to be used is briefly described needed for description of the prior art, it should be apparent that, drawings in the following description are only
